380V 5.5-132kW Variable Frequency Drive Inverter SP600 PT100 PTC Temperature Detection
The SP600 series integrated air compressor unit highly integrates air compressor control technology and variable frequency drive technology. It features a large color touchscreen display, simple wiring and debugging, and easy operation. The control circuit terminals use pluggable terminals with anti-misinsertion design. The product boasts high integration: a built-in 220V AC power supply and provides 24V DC external output. It also features a high degree of intelligence with comprehensive alarm functions, such as input and output phase loss alarms, phase sequence error alarms, high motor and compressor head temperature alarms (PT100 and PTC detection), inverter overload alarms, overcurrent alarms, overvoltage alarms, undervoltage alarms, etc.
- Control: Open‑loop vector, V/F, PM motor compatible
- Frequency range: 0–599Hz
- Carrier frequency: 0.5–8kHz, auto‑adjusted by load
- Power coverage: 220V 3.7–75kW; 380V 5.5–132kW
The SP600 ensures stable running, high torque at low speed, and reliable overload protection, making it ideal for energy‑saving and intelligent upgrading of screw air compressors.
